I know what you mean, and I agree with the idea.
Unfortunately I think it's impossible to implement, especially on such
embedded processors with their high level of pin multiplexing.
For example, if you want to include testing of the FEC ethernet
driver, you will probably fail to test the second USB port. I think
it's simply not possible to test all possible options in a single
kernel configuration - first it doesn't work (for example because of
pin multiplexing issues), second you will likely not be able to find
hardware that implements all features at once.
My dream is to have a distributed test environment - a framework
which can be used for automatic testing which includes building and
running the code on a set of systems, and which will then report the
test results to a central location.
We have the same problem (probably to a much higher degree) in
U-Boot; nobody can test all board configurations because nobody has
all the cross-tools installed nor the 500+ boards available.

again, some distributed test tool might help - we would get not only
information abouyt test results, but also which configurations have
been tested how frequently.

Maybe my expectations for "full featured' are just too high..

Well, that's too bad. Why penalize all platforms for it?

Either go through -mm where Andrew can keep it applied in appropriate
order and send upstream, or just merge it late. It's a new driver, and
they're normally OK to go in a little later. That might be the easiest
solution in this case.

I sent it to Ben with netdev on CC because you asked the various people
sending NEWEMAC patches to you to find a single person.
So from now on, what are we going to do? It seems we're playing net

It does? Grrr... I thought that had been fixed and the only reason
the device_type was still needed was because some u-boot versions
needed it. But you're right, that's not the case.

I don't think this example really applies. Yes, I agree that I cannot
test all the functions, but that does not preclude building in all the
drivers and making sure that they don't cause a conflict by just being
present. For instance, I can build a single kernel image right now
that should boot and fully run on the Efika, lite5200, tqm and motion
pro boards (although the Efika has a different wrapper). I can only
test it on the Efika and lite5200 boards and I have to rely on other
people for the boards I don't have. If it breaks; I expect to receive
an irate email in my Inbox telling me to fix it!
pin multiplexing shouldn't be an issue at all. Only the devices which
are instantiated in the device tree will actually get initialized so
if the pins aren't hooked up then it shouldn't be in the tree.
Ideally, the bootloader should take care of the pin multiplexing
setup, but even if it doesn't it can be setup by platform code and
CONFIG_MULTIPLATFORM supports building multiple platforms into a
single image (within a processor family of course; you can't build a
405+6xx multiplatform kernel.) tqm, motionpro and cm boards can all
use simple platform because they all have good firmware ports that
setup the hardware correctly in the first place. lite5200(b) does not
because there are quite a few lite5200 boards 'in the wild' with
firmware that doesn't setup the board the way it should be (or at
least the way Linux likes it).

I'm happy to collect the patches. I said I would do it, I was just taken

We would have to make that pSeries specific for now I suppose...
We don't have a way to know that there "can" be an EHEA right ? It may
not be in the device-tree at boot and dynamically added to the
partition... And we can't dynamically "demote" the ioremap area like we
do for userspace as we have no tracking of bolted entries hashed in
early during boot (I plan to fix that but that will take a while).

Ben.

If dtc's command line arguments are invalid, it prints a usage message

Ok. Either way, if it helps someone I'd be happy to roll them into a
newemac branch in my git tree.

Sorry... they were CC'd to me and netdev, Stefan had previously
contributed acceptable patches, and the patches looked OK, so... :)

Actually, I looked again and tweaked a few details in the patch (it
was duplicating an existing clause in the wrapper script). I'm just
about to post the edited version which I've tested in my environment.

* [PATCH][POWERPC] bootwrapper: Add entries for tqm8540 and sbc85xx
From: Grant Likely @ 2008-03-18 5:13 UTC (permalink / raw)
To: bunk, paul.gortmaker, galak, paulus, linuxppc-dev, linux-kernel
From: Paul Gortmaker <paul.gortmaker@windriver.com>
The wrapper script didn't have entries for the TQM8540 board and the
SBC8548 or SBC8560 boards. I've assumed that the TQM8540 console is
8250 based and not CPM based by looking at its defconfig. There was
also a trailing * on the TQM8555 entry that I removed too.

Paulus; this fixes the broken defconfig issues that Adrian raised. Can you
please pick this up for merger into 2.6.25?
Thanks,

Sure they were fine, it's just a matter of getting the right

Now, I'll collect the remaining ones and will send them for

Yes.
This is not necessary for your patch, but would be a nice cleanup later.
N.B. this struct is alos used by users of cpm2_set_pin().

OK. Another thought about this. Shouldnt this table go in the dts?
A device node like
cpm_pin {
pins = <port pin flags>;
};
would be nice, or?
